The Lowdown
Alright, let’s break down the surf at Lakey Pipe (Lakai-Pipe). It’s a reef break, meant for the experienced crowd, and it’s exposed to the swell. We’ve got a solid run of clean, consistent surf on the menu, starting right now, Saturday afternoon, and going strong for two weeks.
Water temp is about 80°, which is normal for this time of year.
Starting off Saturday afternoon, we’ve got a 5 ft swell from the SW with a 14-second period. That’s a long-period groundswell packing some serious energy. The wind is light and cross-off, so the waves are gonna be clean and lined up. This is great for experienced surfers, but 5 ft is manageable for a strong intermediate. Keep in mind, that period over 14 seconds means the sets are a bit more spaced out, but the shape will be top-notch on that reef.
Sunday morning steps it up: 6 ft from the SW, with an 18-second period – that’s some proper long-period juice. The wind stays light and cross-off. This is a standout session for anyone who can handle the power and the longer waits. Sunday afternoon, the swell jumps to 8 ft with the same 18-second period, but the wind picks up a little. It’s still clean, but the size is getting into expert territory.
The whole first week holds that quality. Monday and Tuesday have the swell hanging around 6 ft to 6 ft, with periods from 14 to 16 seconds, and those light cross-off winds keeping it glassy. Wednesday and Thursday follow the same script. It’s about as consistent as it gets for quality.
The best of the best comes in the second weekend. Sunday, September 20th, the morning session has a 6 ft SW swell with a 17-second period and barely any wind. That’s a classic, powerful reef wave in perfect condition. But the real standout, the one to really plan for, is Friday, September 25th. The morning brings a 7 ft SSW swell with a 16-second period and light wind. The afternoon cranks it up to 8 ft, same direction and period. That afternoon is the peak of the entire forecast – clean, powerful, and absolutely prime for experts.
A word of caution: Saturday, September 26th sees the swell hitting 10 ft with an 18-second period. That is too big for this break unless you’re a seasoned big-wave charger. The energy will be enormous.
After that, the last week tapers down a bit. Sunday the 27th still has a 8 ft SSW swell and light wind, so the quality remains strong for those who want it.
The takeaway: this is an incredible two-week window. Mark Sunday the 20th for a classic day, and circle Friday the 25th as the absolute standout. Just know the 26th is a big-wave day only. For everyone else, it’s a fantastic run of surf.

Information about the Lakey Pipe Surf forecast
The above surf forecast table for Lakey Pipe provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Lakey Pipe can be found by selecting the local surf guide option on the grey menu. Our Lakey Pipe surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Lakey Pipe) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Lakey Pipe may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
